This route, however, is dis-cussed by Hartel (Fig. 179). This would seem a more dangerous route, and not likely to lead tothe foramen rotundum, but above it. The original route, as advocated by Prof. Matas, traverses the orbitfor but a short distance, as the needle soon passes out of this cavity intothe sphenomaxillary fissure (Figs. 177, 178). If the sphenomaxillary fissures are observed, they will be seen torun at right angles to each other and about on a horizontal plane; THE HEAD, SCALP, CRANIUM, BRAIN, AND FACE 5 their axes if continued back would meet over the body of the sphenoidbone, and if projected forward would emerge at the inferior externalangle of the orbit; also, that the axis of this fissure, if raised to a slightly.

The axis of the foramen rotundum, if viewed from within the skull,passes downward, forward, and outward, and passes through the
